<h1 class="topictitle1">Function Overview</h1>
<div><ul><li>Full backup: <span id="TIDB_00072__en-us_topic_0000001862053249_ph48664393114">backs up all data at a specific point in time, regardless of whether the data has been modified since the last backup. In the case of large data volumes, this backup type may take a long time and occupy a large amount of storage space.</span></li><li>Log backup backs up archived database operation logs. To manually back up logs, ensure that a full backup copy exists.</li><li>Copy verification: verifies the integrity of a copy after the backup is complete or before the copy is used for restoration. </li><li>Source deduplication: deduplicates backup data at the source end before the data is sent to the target end. This technology saves network transmission bandwidth and storage space. Only OceanProtect X series backup appliances and OceanProtect E1000 (with the OceanProtect used as backup storage) support source deduplication.</li><li>Backup link encryption: encrypts transmitted data during data backup to ensure data security. </li><li>Transmission and storage encryption: adopts the AES256 encryption algorithm to encrypt backup data.</li></ul>
